Supplement Restraint System (SRS) “AIR BAG”
and “SEAT BELT PRE-TENSIONER”

The Supplemental Restraint System “Air Bag” and “Seat Belt Pre-tensioner”, used along with a seat belt, help
to reduce the risk or severity or injury to the driver and front passenger in a collision. The Supplemental
Restraint System consists of an air bag module (located in the center of the steering wheel and on the instru-
ment panel on the passenger side, where fitted), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable. Information necessary to service the system safely is included in the
BT section of this Service Instruction.

WARNING:

I

To avoid rendering the SRS inoperative (which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation), all maintenance must be per-
formed by an authorized NISSAN dealer.

I

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.

I

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Instruction. SRS wiring harnesses (except “SEAT BELT-TENSIONER” connector) can be iden-
tified with yellow harness connector and with yellow harness protector or yellow insulation tape
before the harness connectors.

Precautions

I

Use only “DOT 4” fluid from a sealed container.

I

Never reuse drained brake fluid.

I

Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.

I

To clean master cylinder parts, disc brake caliper parts or
wheel cylinder parts, use clean brake fluid.

I

Never use mineral oils such as Petrol or kerosene. They
will ruin rubber parts of hydraulic system.

I

Use flare nut wrench when removing and installing brake
tubes.

I

Always torque brake lines when installing.

I

Burnish the brake contact surfaces after refinishing or
replacing drums or rotors, after replacing pads or linings,
or if a soft pedal occurs at very low speed. Refer to “Brake
Burnishing Procedure”, “Check and Adjustment”, BR-5.

WARNING:

I

Clean brakes with a vacuum dust collector to minimize risk
of health hazard from airborne materials.

I

Avoid prolonged and repeated skin contact with brake
fluid.

I

Wear protective clothing, including impervious gloves.

I

Where there is a risk of eye contact, eye protection should
be worn — for example chemical goggles or face shield.

PRECAUTIONS AND PREPARATION

Checking Brake Fluid Level

I

Check fluid level in reservoir tank. It should be between Max.
and Min. lines on reservoir tank.

I

If fluid level is extremely low, check brake system for leaks.

I

When brake warning lamp comes on even when parking brake
lever is released, check brake system for leaks.

Checking Brake Line

CAUTION:

If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration

or other damage. Replace any damaged parts.

2. Check for oil leakage by fully depressing brake pedal while

engine is running.

Changing Brake Fluid

CAUTION:

I

Refill with new brake fluid “DOT 4”.

I

Never reuse drained brake fluid.

I

Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately. DO
NOT RUB IT OFF.

1. Connect a vinyl tube to each air bleeder valve.
2. Drain brake fluid from each air bleeder valve by depressing

brake pedal.

3. Refill until new brake fluid comes out of each air bleeder valve.

Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to “Bleeding Brake System”, “BRAKE
HYDRAULIC LINE”, BR-8.

Brake Burnishing Procedure

Burnish the brake contact surfaces according to the following pro-
cedure after refinishing or replacing rotors or drums, after replac-
ing pads or linings, or if a soft pedal occurs at very low mileage.

CAUTION:

Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31

MPH).

2. Use medium brake pedal/foot to bring the vehicle to a com-

plete stop from 50 km/h (31 MPH). Adjust brake pedal/foot
pressure such that vehicle stopping time equals 3 to 5
seconds.

3. To cool the brake system, drive the vehicle at 50 km/h (31

MPH) for 1 minute without stopping.

4. Repeat steps 1 to 3 for 10 times or more to complete the

burnishing procedure.
